Middy JWT Authorization Middleware

library 6.3.0 ·javascript
verified Jun 17, 2026

middy-middleware-jwt-auth is a specialized middleware designed for the Middy.js framework, enabling JSON Web Token (JWT) authorization for AWS Lambda functions. Inspired by `express-jwt`, it simplifies the process of verifying JWTs and injecting the decoded payload into the Lambda `event.auth` object. The current stable version is `6.3.0`. The library follows the Middy.js release cadence, frequently updating to support new major versions of `@middy/core`. Key differentiators include its tight integration with the Middy ecosystem, robust type definitions for TypeScript users, and customizable token extraction and verification options, including support for various encryption algorithms and asynchronous secret retrieval. It aims to provide a reliable and easy-to-use solution for securing serverless API endpoints with JWTs.
